As for OP, there’s a option you can enable in your settings that hides your profile, post history, and makes it a little bit of a hurdle to get to someone’s armory, though not entirely.
Here’s my thread on showing how to do so, in case you’re curious: You can hide your profile and presence
If you hover your mouse over someone’s name, you can still see what realm they are from. So, if you go to your armory and type in their realm name and character name in the URL, you’ll still access their armory.
I don’t like the privacy change and don’t understand the big fuss over “muh privacy” but more options, the better. The downside, if I can’t see your post history and you’re trying to make a sound argument, it’s going to seem difficult to see your perspective, if it appears you’re trolling to me, since you’re hiding behind something. Just an example from my end.
